AIR HOSE BGM PRO 50MM fits Keihin /PWK /koso 28 -30, Polini cp 28 – 30

- Product advantages 
- Much more volume than standard airhoses
- Super Strong external ribbing
- Lower drain pipe
- Perfect for both standard and tuned engines
- Uses Original type airbox (or you can add a foam filter)

In comparison with the standard intake hose, the bgm PRO air intake hose has a higher volume on the side of the carburettor.

50 mm (Keihin PWK 28, Polini 28 – 30).

The connection size on the side of the air filter is equal to 42 mm so that you can use the intake hose either with the genuine air filter box or with a foam air filter.
Another significant advantage of the bgm PRO air intake hose is the drain system at the bottom of the intake hose: the fluid expelled from the carburettor does not accumulate in the hose and this prevents the idle speed system from clogging.
